Description

PRIORITY

This application claims priority to India Patent Application No. 201641021755, filed on Jun. 24, 2016, entitled “Mobile Device with Unified Media-Centric User Interface,” the entire disclosure of which is hereby incorporated by reference.

BACKGROUND

Some mobile devices, such as Android smartphones, allow users to save their content in multiple storage locations, such as internal memory, a removable memory card (e.g., a microSD cards), an external storage device (e.g., on-the-go (OTG) dual USB drives), and in various cloud services (e.g., Dropbox, Box, Google Drive, One Drive, etc.). When content is spread across multiple locations, users can easily lose track of their content as they do not get a holistic view of how and where their content is distributed. Also, there is no easy way to move content between these storage end-points. Some mobile device user interfaces are limited to a basic file folder view, which makes navigation between different locations on a mobile user interface complex and frustrating for users. Additionally, the native gallery app on some mobile devices may provide a unified view of the internal and external storage (e.g., microSD) devices but does not offer a view into cloud and OTG drives

DETAILED DESCRIPTION

By way of introduction, the below embodiments relate to a mobile device with a unified media-centric user interface. In one embodiment, the user interface contains one or more of the following features: a unified view of the home screen, navigating between various storage locations, dragging items to collection/folder, pinch and zoom feature, stats shown for each file type, storage usage view from the app, manual and automatic backup, and magic move (keeping a low-resolution version of the original files while moving). Other embodiments are possible, and each of the embodiments can be used alone or together in combination.

Turning now to the drawings, FIG. 1 is an illustration of a mobile device 100 of an embodiment. The mobile device 100 can take any suitable form, such as, but not limited to, a smart phone (e.g., an Apple iPhone, an Android phone), a tablet (e.g., an Apple iPad), a “phablet,” a book reader (e.g., an Amazon Kindle), a digital media player (e.g., an iPod), a game device, a personal digital assistant (PDA), a laptop, a wearable computer (e.g., a smart watch or Google Glasses), and any other mobile device where access to additional memory may be desired. As shown in FIG. 1, the mobile device 100 in this embodiment comprises a controller 120 that runs an operating system 124 that runs one or more applications (e.g., computer-readable program code executable by the controller 120) (such as an app 125 with a unified user interface) that communicate with a common operating system database 129, a battery 140, and a port 150 for a power/data JO connector, a port 160 for a removable memory card, a wireless interface 170, and a touch-sensitive display 180. The mobile device 100 can contain different or additional components, which are not shown in FIG. 1 to simplify the drawing. For example, if the mobile device 100 is a mobile smart phone, the mobile device 100 can include hardware and/or software components to make and place telephone calls. The mobile device 100 can also have a camera, a media player, etc. Of course, these are just some examples, and other implementations can be used.

As shown in FIG. 1, the mobile device 100 has a memory 130, which can store content. Content can take any form, including, but not limited to, photos, videos, music, and data attachments. In addition to the internal memory 130, content can be stored on a removable memory device (e.g., a microSD cards) inserted into the removable memory card connector port 160, an external storage device (e.g., on-the-go (OTG) dual USB drives) connected through the data JO connector port 150, and in various cloud services (e.g., Dropbox, Box, Google Drive, One Drive, etc.) in communication with the mobile device 100 via the wireless interface 170. Any suitable wireless technology, now existing or later developed, can be used, including, but not limited to, 802.11 WiFi, near-field communication (NFC), Bluetooth (including Bluetooth Low Energy (LE), Nike+, ANT, ANT+, ZigBee, Radio Frequency for Consumer Electronics (RF4CE), and Infrared Data Association (IrDA).

FIG. 2 is an illustration of a storage device 200 of an embodiment. This general diagram can describe a removable memory card, an external storage device, or a cloud-based storage device. Of course, different or other components specific to the type of device can be used. As shown in FIG. 2, the storage device 200 in one embodiment contains a controller 210 and non-volatile memory 220. In this embodiment, the controller 210 comprises a host interface 212 for placing the storage device 200 in communication with the mobile device 100, and a memory interface 211 for placing the controller 210 in communication with the memory 220. (As used herein, the phrase “in communication with” (or “operatively in communication with”) could mean directly in communication with or indirectly in communication with through one or more components, which may or may not be shown or described herein.) The host interface 212 can take any suitable form, such as, but are not limited to, a SATA, SATA Express, SAS, Fibre Channel, USB, PCIe, and NVMe interface. The memory interface 211 can also take any suitable form, such as, but not limited to, a flash interface (e.g., Toggle

Mode

200, 400, or 800).

The controller 210 also comprises a central processing unit (CPU) 213, an optional hardware crypto-engine 214 operative to provide encryption and/or decryption operations, read access memory (RAM) 215, read only memory (ROM) 216 which can store firmware for the basic operations of the storage device 240 and an application program interface, and a non-volatile memory (NVM) 217 which can store a device-specific key used for encryption/decryption operations, when used. The controller 210 can be implemented in any suitable manner. For example, the controller 210 can take the form of a microprocessor or processor and a computer-readable medium that stores computer-readable program code (e.g., software or firmware) executable by the (micro)processor, logic gates, switches, an application specific integrated circuit (ASIC), a programmable logic controller, and an embedded microcontroller, for example. Suitable controllers can be obtained from SanDisk or other vendors. Also, some of the components shown as being internal to the controller 210 can also be stored external to the controller 210, and other components can be used. For example, the RAM 215 (or an additional RAM unit) can be located outside of the controller die and used as a page buffer for data read from and/or to be written to the memory 220.

The non-volatile memory 220 can also take any suitable form, as can the internal memory 130. For example, in one embodiment, a memory takes the form of a solid-state (e.g., flash) memory and can be one-time programmable, few-time programmable, or many-time programmable. The memory can also use single-level cell (SLC) or multiple-level cell (MLC). The memory can take the form of NAND Flash memory or of other memory technologies, now known or later developed.

In one embodiment, the app 125 provides a unified media-centric user interface to view and to backup content on a mobile device, microSD Card, on-the-go drive, and/or cloud storage services. As discussed above, Android users can save their content in multiple storage locations, such as internal memory, microSD cards (external), Dual USB drives (OTG), and in various cloud services (like Dropbox, Box, Google Drive, One drive etc.). When content is spread across multiple locations, users can easily lose track of their content as they do not get a holistic view of how/where their content is distributed. There is also no easy way to move the content between these storage end-points using a single application. The following embodiments provide a user interface that can be used to help solve these problems by providing a unified view of all storage locations and automatically categorizing user content into photos, videos, music, and documents, for example. This new interface allows users to understand and manage their storage better and also move content between phone, card, and cloud easily. Moreover, the app also allows users to backup content to the cloud or to the card based on user preference. This provides advantage over other solutions. For example, some other solutions that are currently available to consumers do not follow a media centric/unified view and are often limited to a basic file folder view. This makes navigation between different locations on a mobile user interface complex and frustrating for users. Also, some native Gallery apps offer a unified view of the internal and external storage (microSD) but do not offer a view of cloud and OTG drives. Other solutions do not offer backup based on user preferences to the card, cloud, and OTG drives.

In one embodiment, using the unified media centric user interface of the new memory zone app allows files from various memory sources to be indexed and classified into different file types and shown under a single common user interface. Users can easily toggle between photos, videos, music, and other file types and can also view files from all the storage end points in this unified user interface. The backup flow illustrates in detail the process a user would follow to set up his/her preference while backing up their phone content to various storage end-points.

In one embodiment, a unified view of the home screen is provided. In this embodiment, files from various memory sources are indexed and classified into different file types and shown under a single common user interface. This makes it easier to navigate between various file types such as photos, videos, music, and documents. As such, it is very simple for a non-technical user to use the app.

In another embodiment, the app allows navigating between various storage locations. As shown in the figures, the Navigation drawer will house a secondary option of “Storage Locations”. Hardware and cloud accounts can be available in the storage location tab bar. The tab bar can show all the active hardware and authenticated cloud accounts first, respectively. Following this, the tab bar can show any inactive hardware (hardware that user does not have) and cloud accounts that are not logged in. These will show empty state, as shown in the drawings. Hardware can be listed with SD card first, and then dual drive. Cloud accounts can be listed alphabetically.

In another embodiment, the app allows dragging items to a collection/folder. Multiselecting allows the user to drag the files to a particular collection or folder. As the user starts dragging, selected files can animate and become grouped together into a stack in different ways depending on if it is in file type view or in storage view as explained below.

For a file type: The stack can duplicate above the selected items, as they will not live in their respective file type tab.

For a storage location: The stack can form and leave empty spaces where the selected files were. After the files are dropped into the folder, the remaining files in the view can reorganize to take up the empty spaces.

In another embodiment, the app provides a pinch and zoom feature. This feature allows a user to see photos in month wise and year wise. On zooming, the user can see photos in a 2 column layout from 4 column view, similarly from Yearly view to Monthly view to Daily view. With a pinch to monthly view, the first pinch (zoom out) allows user to see photos month wise. Now tapping in/Zooming in goes to daily view. With a pinch again to yearly view, the second pinch (zooming out) gives a yearly view of photos. One of the drawings shows a 12 column grid view. The user can tap once or zoom out to go back to the Month view and then to Daily view. So, zooming out results in a daily view to a monthly view or a yearly view, and zooming in results in a yearly view to a monthly view to a daily view.

In another embodiment, the app shows stats for each file type. In this embodiment, the total number of files from each memory location are shown along with the particular storage icons on top of the list view or grid view.

In another embodiment, there is a storage usage view from the app. This view will show a list of all storage locations that the user has, with current storage usage. Tapping on each storage item in the list will show the data for each of the individual storage accounts, including the number and amount of storage space used for each file type.

In another embodiment, the app provides manual and automatic backup. Users can backup his/her phone contents to various destinations such as micro SD card, Dual drive and the authenticated cloud storage accounts. The user can either do manual backup or setup automatic backup. The user can select the file types such as photos, videos, music, etc that can be backed up to a particular storage location. The user can also configure when the backup can happen by choosing the day and the time in the settings.

In another embodiment, the app provides a magic move, in which the app keeps the low-resolution version of the original files while moving. In this embodiment, the app can create low-resolution images/videos before moving files from Internal memory to Dual drive. The original file will be moved from the Internal Memory/micro SD card to Dual drive and create low-resolution images/videos in the same source memory location where the original file was there. There are several advantages of have a low-resolution file. For example, the user can view or browse the files in his/her phone when the dual drive is not connected. Also, this frees up space in the internal memory or micro SD card as the low-resolution images/videos will occupy only less space in the memory.

There are many advantages associated with these embodiments. For example, these embodiments can help users organize their contents from various memory sources and can view all files in one common centric media user interface. The embodiments also make it easy for user to do memory management of various memory sources either it can be a local storage or cloud storage. Additionally, since all files from all memory sources are sorted, it is easier for the user to find a particular photo or video. Further these embodiments allow users to backup their phone content to cloud, microSD card or USB drive easily.

These embodiments are further illustrated in the attached drawings.

Finally, as mentioned above, any suitable type of memory can be used. Semiconductor storage devices include volatile storage devices, such as dynamic random access memory (“DRAM”) or static random access memory (“SRAM”) devices, non-volatile storage devices, such as resistive random access memory (“ReRAM”), electrically erasable programmable read only memory (“EEPROM”), flash memory (which can also be considered a subset of EEPROM), ferroelectric random access memory (“FRAM”), and magnetoresistive random access memory (“MRAM”), and other semiconductor elements capable of storing information. Each type of storage device may have different configurations. For example, flash storage devices may be configured in a NAND or a NOR configuration.

The storage devices can be formed from passive and/or active elements, in any combinations. By way of non-limiting example, passive semiconductor memory elements include ReRAM device elements, which in some embodiments include a resistivity switching storage element, such as an anti-fuse, phase change material, etc., and optionally a steering element, such as a diode, etc. Further by way of non-limiting example, active semiconductor memory elements include EEPROM and flash storage device elements, which in some embodiments include elements containing a charge storage region, such as a floating gate, conductive nanoparticles, or a charge storage dielectric material.

Multiple memory elements may be configured so that they are connected in series or so that each element is individually accessible. By way of non-limiting example, flash storage devices in a NAND configuration (NAND memory) typically contain memory elements connected in series. A NAND memory array may be configured so that the array is composed of multiple strings of memory in which a string is composed of multiple memory elements sharing a single bit line and accessed as a group. Alternatively, memory elements may be configured so that each element is individually accessible, e.g., a NOR memory array. NAND and NOR memory configurations are exemplary, and memory elements may be otherwise configured.

The semiconductor memory elements located within and/or over a substrate may be arranged in two or three dimensions, such as a two dimensional memory structure or a three dimensional memory structure.

In a two dimensional memory structure, the semiconductor memory elements are arranged in a single plane or a single storage device level. Typically, in a two dimensional memory structure, memory elements are arranged in a plane (e.g., in an x-z direction plane) which extends substantially parallel to a major surface of a substrate that supports the memory elements. The substrate may be a wafer over or in which the layer of the memory elements are formed or it may be a carrier substrate which is attached to the memory elements after they are formed. As a non-limiting example, the substrate may include a semiconductor such as silicon.

The memory elements may be arranged in the single storage device level in an ordered array, such as in a plurality of rows and/or columns. However, the memory elements may be arrayed in non-regular or non-orthogonal configurations. The memory elements may each have two or more electrodes or contact lines, such as bit lines and word lines.

A three dimensional memory array is arranged so that memory elements occupy multiple planes or multiple storage device levels, thereby forming a structure in three dimensions (i.e., in the x, y and z directions, where the y direction is substantially perpendicular and the x and z directions are substantially parallel to the major surface of the substrate).

As a non-limiting example, a three dimensional memory structure may be vertically arranged as a stack of multiple two dimensional storage device levels. As another non-limiting example, a three dimensional memory array may be arranged as multiple vertical columns (e.g., columns extending substantially perpendicular to the major surface of the substrate, i.e., in the y direction) with each column having multiple memory elements in each column. The columns may be arranged in a two dimensional configuration, e.g., in an x-z plane, resulting in a three dimensional arrangement of memory elements with elements on multiple vertically stacked memory planes. Other configurations of memory elements in three dimensions can also constitute a three dimensional memory array.

By way of non-limiting example, in a three dimensional NAND memory array, the memory elements may be coupled together to form a NAND string within a single horizontal (e.g., x-z) storage device levels. Alternatively, the memory elements may be coupled together to form a vertical NAND string that traverses across multiple horizontal storage device levels. Other three dimensional configurations can be envisioned wherein some NAND strings contain memory elements in a single memory level while other strings contain memory elements which span through multiple memory levels. Three dimensional memory arrays may also be designed in a NOR configuration and in a ReRAM configuration.

Typically, in a monolithic three dimensional memory array, one or more storage device levels are formed above a single substrate. Optionally, the monolithic three dimensional memory array may also have one or more memory layers at least partially within the single substrate. As a non-limiting example, the substrate may include a semiconductor such as silicon. In a monolithic three dimensional array, the layers constituting each storage device level of the array are typically formed on the layers of the underlying storage device levels of the array. However, layers of adjacent storage device levels of a monolithic three dimensional memory array may be shared or have intervening layers between storage device levels.

Then again, two dimensional arrays may be formed separately and then packaged together to form a non-monolithic storage device having multiple layers of memory. For example, non-monolithic stacked memories can be constructed by forming memory levels on separate substrates and then stacking the memory levels atop each other. The substrates may be thinned or removed from the storage device levels before stacking, but as the storage device levels are initially formed over separate substrates, the resulting memory arrays are not monolithic three dimensional memory arrays. Further, multiple two dimensional memory arrays or three dimensional memory arrays (monolithic or non-monolithic) may be formed on separate chips and then packaged together to form a stacked-chip storage device.

Associated circuitry is typically required for operation of the memory elements and for communication with the memory elements. As non-limiting examples, storage devices may have circuitry used for controlling and driving memory elements to accomplish functions such as programming and reading. This associated circuitry may be on the same substrate as the memory elements and/or on a separate substrate. For example, a controller for memory read-write operations may be located on a separate controller chip and/or on the same substrate as the memory elements.

One of skill in the art will recognize that this invention is not limited to the two dimensional and three dimensional exemplary structures described but cover all relevant memory structures within the spirit and scope of the invention as described herein and as understood by one of skill in the art.

It is intended that the foregoing detailed description be understood as an illustration of selected forms that the invention can take and not as a definition of the invention. It is only the following claims, including all equivalents, that are intended to define the scope of the claimed invention. Finally, it should be noted that any aspect of any of the preferred embodiments described herein can be used alone or in combination with one another.
